WILLIAM JAMES RUSSELL ALLAN, OF .VAVERLEY, NEAR SYDNEY, NEW SOUTH WALES,AUSTRALIA.

BESILIENT PROTECTOR FOR HEELS ANDSOLES.

Application filed February 26, 1924. Serial No. 695,180.

To all whom it may concern:

Be it known that 1, WILLIAM JAMns RussnLL ALLAN, a subject of the Kingof Great Britain, residing at Waverley, near Sydney, in the State of NewSouth Wales and Commonwealth of Australia, have invented a new anduseful Improved Resilient Protector for Heels and Soles, of which thefollowing is a specification.

This invention relates to protectors for attaching or afiixing to thesoles and heels of boots, shoes and the like and consists inconstructing thyqwlflmwfl flf any other suitab e resilient orcompressible material in dished or conveXb-concave formation, with orwithout an inward screw head depression or recess in the crown, in orderthat the cushioning effect thereof to the feet of the wearer will beincreased thus resulting in greater comfort and resilience than has beenobtainable with resilient protectors as hitherto constructed and inorder that the durability of the protector will be prolonged thusreducing the cost, and in combining a protector with a heel or toe orsole piece.

And in order that the invent-ion and a practical application thereofwill be readily understood the same will now be described with referenceto the accompanying drawings in which Figure 1 is a. diametricalsectional elevation of the improved resilient protector,

Figure 2 is a reversed plan of the same,

Figure 8 is a diametrical sectional elevation of a heel piece combinedwith a protector,

Figure 4 is a reversed plan of the same, and

Figure 5 is a plan of a boot sole and heel with protectors and heelpiece applied thereto.

The protector 6 is conveXo-concave preferably .ith splayed edge or rim 7has an inward depression or recess 8 in the crown for reception of thehead of the screw 10 by which the protector is secured to the sole orheel and to ensure that the protector will not be flattened by the crownbeing drawn by said screw to the sole or heel in the affixing, and hasinternal reinforcing and distancing ribs or heads 9 which prevent theprotector being wholly flattened by weight thereon and thus ensure readyrelease from a surface whereon the protector contacts and is pressed asin walking.

The protector 6 may be combined with a heel member 11 formed of the samemater al to the plan shape of the boot, etc. heel and with a recess 12of slightly greater diameter than the protector to receive the latterand allow for limited expansion therein. In the manufacture the heelmember and protector are moulded together with a narrow junction of thematerial at opposite sides so that after the protector has worn at therear of the heel said junctions may be severed and thus allow theprotector to be revolved so that an unworn portion thereof will bepresented to the rear of the heel.

In afiixing the protector to a sole or heel a washer of suitablematerial and shape may be inserted in the recess 8 and a screw isinserted through the washer and the bottom of said recess 8 into saidsole or heel.

In use as the protector contacts with the surface walked upon air isimprisoned under the protector and as weight flattens it such air iscompressed and some escapes thus increasing the cushioning effect, theinternal "lbs 9 preventing total flattening of the protector and raisingthe edge or rim thereof as soon as weight is relieved thus breaking anysuction or gripping effect and ensuring ready release of the protectorfrom said surface.

I claim 1. A resilient protector for the soles of shoes, comprising aconcavo-convex member of flexible material having a concentricdepression extending inwardly from its convex side and provided on itsconcave side with symmetrically disposed means for preventing contact ofsaid side with the shoe sole.

2. A resilient protector for the soles of shoes comprising aconcavo-convex member of flexible material having a concentricdepression extending inwardly from its convex side and provided on itsconcave side with symmetrically disposed ribs integral therewith forpreventing contact of said side with the shoe sole.
